do hereby azd'eelarei ther-following to beaj fll, clean-and exactdeseription of the inventionusuch as :will enable others' skilled appertains tomake and use the same. i My invention relates tofountain pens equipped with compressible `ink sacks, which sacks are filled by :suction of mk into thesame after thesackshave been collapsed. It has i been cu stomary heretofore, to'equip pens of this 'kind Withg pressure-bars or followers interposed.between'theink sackshand the barrels; of the p'ens; each s follower being attachdeto-aspring whichfwill return the. ;pressurebar to its normal; position 'when the compressing action is relaxedg and also to equip the barrels of s uchfl p'ens with levers actuatingathe spressureb'ars* {(either` drectly orthrough the intermediatefspring) to ef :feet the said compression. In`"using such pens, it is important that' the saok should be compressed as fully as possiblewvhen 'the tip of the penisinsertedintothe supply of ink for filling the pen; as the sack otherwse will not receive its maximum spply of ink. To, accomplish this maximum filling, it isdesirableto :stop the movement ;of the actuating-leve-` in'thezpositidn -;at 'which' it afi'ects theem fiximum?compression .jof the ink sacl, forwhih purposes penshave heretofore beenmzde with stop lformat'ions either upon the pressure-,bars 'or -'upon 1 the 'springs carrying said r pressui eeba'rsiwhieh frfnntion `'Would %0 engageth innifrenof th ctutingleve u etto* stop: thelatter tfcwstop r'jngementsj have the.

Fig. 10 "is an enlarged perof Figs. 6 and 8; hlemy invention may be applied to pens having various types of pressure-bars and of 'supports for the letter, itsparticuirly adapted for use in connection with the spring-supported pressurebar invented by Harvey Gr. Craig and shown in hisf'copending application, Serial No. 830536! In this 90 i constructiom the fountainpenconsist's of sa barrel 1 having& closed end adapted slid-' `h bar-reh fces 'slt 10 xtending .longitudinally 'ofthe barrel invone side of the'ltter, which slot substantially h'ouses aslever 11 pivoted upon 'a pin 12 extendiig through-theberrel transvrely-of 116 fragmentary plan views showing i of. Fig. 6. Fig. 9'

the lever s substantially fiush With the sur- I face of the barrel. Adjacent to the longer 'end of the lever, the barrel 1 is equippel' with a deprssion 13 permitting a finger nail or any sharp instrument to be inserted under the extreme end lat of the lever for raising the lever, while the shorter end of the lever is considerably longer than the thickness of the latter, so that this shorter end will project transversely into the barrel when the lever is moved into its operative position as shown in dotted lines at 15 in Fig. 2.

It will b'e evidentthat if the lever were moved still farther (as shown by dotted lines 16), the short end of the lever would no longer project as far into the barrel,

I hence the maximum compressing of the ink ment of the lever.

sack would no longer be efi'eCted. To avoid such an excessive movement ofthe' lever,`I equip the latter With at least one stop formation substantially out of the path of the spring-bar 8 when the lever is in its normal I poston,

but so'disposed as to ,engage a portion of the barrel 1 when the lever is moved to its right-angle position 15. In.

the embodiment of Fig 1 twosuch stop formations are shown, consisting of mountig tf the lever by widening the shorter end of said lever, the extra width being housed by the correspondingly widened portion of the forward end of the slot 10. It will be evdent from Fig. 4 that the shoulders 17 will engage inner surfaces of the barrel at opposite sides of the'slot 10 and directly under pivot 12 when thezlever has been moved to its maximum pisureactuating' position, leverin the position in which .it is most effective for filling the saek of the pen.-

Instead of widening the entire short end` of the lever, the stop formation may be pro duced upon the same by Wideningonly an inner portion presenting at least one arm i 18 extending intothe barrel directly underneath the shorter end of the lever and adjacent to the pivotal mounting of the latter as shown in Figs. 5, 7 and 9. Or, the widening may be effected by swaging a por- .tion of the short end of the lever, as shown in Figs. 6, 8 and 10, thereby providing plugs 19 which will also present shoulders adapted' to engage innersurfaes of the barrel 1 at opposite sides of the slot to limit the move- This latter Construction has the advantage that the widened'part of the slot may be cheaply made by boring a hole radially of the.barrl and omewhat larger in diameter than the width of the slot,

the shouldersi ormed adjaeent to the pivotalthereby stoppii the while the lever of Fig. 3 will require a slot I having a wide portion of rectangular sec-` tion.

It will be evident in each of the cases illustrated', that the stopping is effected by the simultaneous engagement of portions of the lever with pa'ts of the barrel at opposite sidesf the slot, thereby avoiding any tendency toward a twisting of the lever and a consequent over-straining of the necessarily delicate pivotal mounting also that the stopping in each case is entirely independent of the spring or pressure-bar construction, thereby avoiding the strain imnormal engagement with the section 3, and

possibly would cause the edge of the said collar to damage the forward end of the ink sack. lVith my Construction, no such strain will be imposed upon the monnting of the pressure-bar, as the. strain is entirely taken by the barrel of the pen. However, I do not wish to be limited'to the use of my invention in connection with compressing arrangements of the type invented hy Mr. Craig nor to .the details herein disclosed, as

it will be evdent that these may be modified in many ways without departing from the spirit of my invention.

I claim as my invention:

1. In `a fountain pen, the combination with a barrel having a slot in one side thereof, of a compressible ink sack and a follower for said sack both housed by the barrel, the follower facing said slot; and a lever of the first class pivoted to said barrel and normally having at least its longer end housed by said slotg the shorter end of said lever engagng said follower when the lever is moved about its pivot, thereby actuating the follower to compress the sack; said lever having a portion wider than the part ,of the slot housing the longer end of the lever, said wider portion so disposed as to engage the barrel adjacent to the last named part of the slot, when the lever is moved to actuate the follower, thereby limiting the said follower-actuating movement of the lever.

2. In a fountain pen, the combination' With a barrel having a slot in one side thereof, of a compressible ink sack and a follower for said sack both housed by the barrel, the follower facing said slot; and a lever of the first classpivoted to said barrel and 'having at least its longer end normallyhoused by said slot; the shorter end of said lever en-.

the follower to compress said sak; said lever'havng a porton WIde' than thepart 'of the slot housing the' longer end 'of the V level', :said Wider portion so disposed as to ongage the barrel adjacent to and at both sides of the last named part of the slot, When the level' is'moved to actuate the followe', the'eby linting the said follower-actuatng movement of the level'.
